The intertwining between spin, charge, and lattice degrees of freedom can give rise to unusual macroscopic quantum states, including high-temperature superconductivity anomalous Hall effects. Recently, a charge density wave (CDW) has been observed in the kagome antiferromagnet FeGe, indicative possible physics. An outstanding question is that whether magnetic correlation fundamental for spontaneous spatial symmetry breaking orders. Here, utilizing elastic high-resolution inelastic x-ray...
Altermagnetism (AM), a newly discovered magnetic state, ingeniously integrates the properties of ferromagnetism and antiferromagnetism, representing significant breakthrough in field materials. Despite experimental verification some typical AM materials, such as MnTe MnTe_{2}, pursuit materials that feature larger spin splitting higher transition temperature is still essential. Here, our research focuses on CrSb, which possesses Néel up to 700 K giant near Fermi level (E_{F}). Utilizing...

Abstract Exotic quantum states arise from the interplay of various degrees freedom such as charge, spin, orbital, and lattice. Recently, a short-ranged charge order (CO) was discovered deep inside antiferromagnetic phase Kagome magnet FeGe, exhibiting close relationships with magnetism. Despite extensive investigations, CO mechanism remains controversial, mainly because behavior hinders precise identification superstructure. Here, combining multiple experimental techniques, we report...

Many correlated metallic materials are described by Landau Fermi-liquid theory at low energies, but for Hund metals the coherence scale T_{FL} is found to be surprisingly small.

Hund metals have attracted attention in recent years due to their unconventional superconductivity, which supposedly originates from non-Fermi-liquid (NFL) properties of the normal state. When studying using dynamical mean-field theory, one arrives at a self-consistent "Hund impurity problem" involving multiorbital quantum with nonzero coupling interacting metallic bath. If its spin and orbital degrees freedom are screened different energy scales, $T_\mathrm{sp} < T_\mathrm{orb}$,...
